2, Peb cov txheej txheem tseem ceeb rau kev ncua lub neej kev pab cuam ntawm kev lag luam nres
Lub ntsiab lus tseem ceeb rau kev ua haujlwm ntev yog txo qis kev hnav thiab tsim kua muag, zam kev puas tsuaj txawv txav, thiab tswj xyuas cov haujlwm zoo. Peb cov txheej txheem hauv qab no yuav tsum tau ua raws li lub sijhawm ntev:
Tswv yim 1: Kev tswj xyuas ntawm kev sib txhuam khub hnav kom tsis txhob "hnav hnyav"
Kev sib txhuam khub (brake pads thiab nres lub log / discs) yog cov khoom siv ntawm tus nres uas hnav sai tshaj plaws, thiab tswj nws tus nqi hnav yog tus yuam sij rau kev ncua nws txoj sia.
- Kho kom raug nres tshem tawm:Teem lub nres tshem tawm raws li cov khoom siv phau ntawv (feem ntau 0.5-2mm). Yog tias qhov kev tshem tawm tsawg dhau, nws yuav ua rau "nres ntawm kev ua haujlwm" (kev sib txhuam tsis tu ncua ntawm cov pawm nres thiab lub log nres), thaum lub clearance loj dhau lawm, nws yuav txo qhov braking torque. Nws raug nquahu kom kuaj xyuas ib zaug txhua lub hlis twg thiab ntsuas qhov kev tshem tawm los ntawm kev kho cov ntsia liaj qhov rooj lossis thawb pas nrig.
-Ua kom qhov chaw sib txhuam kom huv si thiab qhuav:Nws yog nruj me ntsis txwv tsis pub cov roj stains, dej, thiab hlau khib nyiab kom ua raws li qhov sib txhuam ntawm qhov chaw - cov roj stains yuav txo qhov kev sib txhuam coefficient (ua rau tsis txaus braking quab yuam, yuav tsum muaj zog braking torque thiab exacerbating hnav), thiab cov khib nyiab hlau yuav ua rau "abrasive hnav" (scratching lub log). Tsis tu ncua siv cov cua compressed qhuav los tshuab qhov kev sib txhuam hauv lub neej txhua hnub. Yog hais tias nws yog stained nrog roj, nws yuav tsum tau so nrog cawv los yog ib tug tshwj xeeb ntxuav tus neeg sawv cev.
-Tsis txhob nres thaum muaj xwm ceev:Thaum muaj xwm txheej ceev, cov kev sib txhuam sib txhuam tam sim ua kom muaj qhov kub thiab txias (txog 300-500 degree), uas tuaj yeem ua rau cov ntaub thaiv "kub tawg" (txo qis hauv kev sib txhuam coefficient) thiab txawm tias "kub tawg"; Nyob rau tib lub sijhawm, qhov kub thiab txias yuav ua rau kom cov oxidation ntawm lub log nres, ua rau "txheej plhaub tawv" (uas yog nquag mus rau detachment thaum lub sij hawm tom ntej braking thiab exacerbates hnav). Nws raug nquahu kom tswj hwm kev ceev ceev los ntawm "incremental braking" lossis "graded braking", thiab tsuas yog siv thaum muaj xwm txheej ceev thaum muaj xwm txheej ceev.
Tswv yim 2: optimize tus tsav tsheb thiab kev sib txuas system kom txo tau "kev puas tsuaj ntxiv"
Yog hais tias lub zog tsav tsheb (hydraulic / pneumatic / electromagnetic) thiab cov khoom sib txuas (bolts, pins) ntawm tus nres yog nyob rau hauv ib qho kev txawv txav, nws tuaj yeem ua rau tsis ncaj ncees rau kev hnav ntawm kev sib txhuam thiab ua rau cov khoom tawg.
-Kev saib xyuas tsis tu ncua ntawm lub tshuab tsav:
•Hydraulic tsav:Tshawb xyuas cov viscosity ntawm cov roj hydraulic txhua 6 lub hlis (yog tias qhov viscosity txo qis, nws yuav ua rau cov lus teb ntawm lub laub pas nrig qeeb), kev huv ntawm cov roj (cov impurities yuav thaiv lub tog raj kheej, ua rau cov pas nrig rub tau daig), thiab hloov cov roj hydraulic ib xyoos ib zaug; Tshawb xyuas kev laus ntawm lub nplhaib sealing (tshwj xeeb tuaj yeem ua rau lub zog nres tsis txaus, nce roj siab, thiab hnyav lub tog raj kheej hnav).
• Pneumatic tsav:txhua lub lim tiam (cua cia tank, lim) kom tsis txhob muaj dej corrosion ntawm lub tog raj kheej; Tshawb xyuas lub trachea rau cov kab nrib pleb thiab cov pob qij txha rau cov pa xau txhua lub hli (cov pa xau tuaj yeem ua rau tsis txaus thawb pas nrig thiab nres nres tsis tiav).
•Electromagnetic tsav:Tshawb xyuas cov txheej txheej rwb thaiv tsev ntawm cov kauj txhua lub hlis twg (yog tias puas lawm, nws yuav ua rau luv luv thiab hlawv), ntxuav lub ntsej muag ntawm lub ntsej muag (xeb tuaj yeem ua rau xoob xoob, suab nrov txawv txav, thiab kub dhau).
-Txhim kho qhov fastening thiab lubrication ntawm cov khoom sib txuas:
• Tightening:Siv lub torque wrench los xyuas cov kev sib txuas ntawm lub braking caj npab thiab lub hauv paus txhua lub hlis, thiab nruj me ntsis raws li cov lus qhia (cov bolts xoob tuaj yeem ua rau lub brake caj npab hloov, ua rau tsis sib xws ntawm cov nres nres);
• Lubrication:Cov roj lubricating tshwj xeeb (lithium raws roj lossis siab - roj roj) yuav tsum tau ntxiv rau cov khoom txav xws li shafts thiab bearings txhua 2 lub hlis kom tsis txhob muaj cov khoom sib tsoo thiab deformation los ntawm kev hnav qhuav. Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias lubricating qhov kev sib txhuam nto yog nruj me ntsis txwv tsis pub thiab tsuas yog tsis muaj kev sib txhuam txav yuav tsum tau lubricated.
Tswv yim 3: Tsim kom muaj "kev saib xyuas qib" mechanism kom tsis txhob "khiav nrog teeb meem"
Feem ntau cov nres nres tsis ua haujlwm yog "qib" (los ntawm kev hnav me me mus rau qhov tsis ua haujlwm), thiab tsim kom muaj kev saib xyuas kev ua haujlwm tau zoo tuaj yeem txheeb xyuas cov kev phom sij zais cia ua ntej, zam cov teeb meem me me los ntawm kev nce mus rau qhov ua tsis tiav loj.
-Kev tshuaj xyuas txhua hnub (ib hnub ib zaug):Ua tiav los ntawm tus neeg teb xov tooj, nrog rau kev tsom mus rau kev kuaj xyuas: ① Tsis muaj lub suab nrov txawv txav thaum lub sijhawm braking (xws li "screaming" lossis "stuttering", uas tej zaum yuav yog vim qhov tsis sib xws ntawm lub nres nres lossis cov khoom txawv teb chaws daig); ② Txawm tias cov cuab yeej ruaj khov tom qab braking (txawm tias muaj dov); ③ Tshawb xyuas cov roj stains pom tseeb thiab hnav cov cim ntawm qhov sib txhuam.
-Kev tshuaj xyuas tsis tu ncua (ib hlis ib zaug):Ua tiav los ntawm kev saib xyuas cov neeg ua haujlwm, ua tiav kev tshuaj xyuas raws li "cov ntsiab lus tshuaj xyuas", sau cov ntaub ntawv tseem ceeb (xws li nres nres thickness, thawb pas nrig mus ncig, coil kub), thiab muab piv nrog cov ntaub ntawv keeb kwm los txiav txim qhov kev coj cwj pwm (xws li nres lub ncoo hnav ntawm 0.5mm ib hlis twg, yog tias nws dheev nce mus rau 1mm, qhov ua rau yuav tsum tau tshawb xyuas).
-Kev kho dua tshiab txhua xyoo (ib xyoos ib zaug):Disassemble cov khoom tseem ceeb xws li lub log tsheb, thawb pas nrig, thiab cov pas dej, xyuas qhov roughness ntawm lub log tsheb (yog tias hnav tshaj li tus qauv, nws yuav tsum tau kho los ntawm kev tig), lub caij nplooj ntoos hlav elasticity (kuaj nrog lub ntsuas ntsuas, yog tias qhov attenuation tshaj 20%, nws yuav tsum tau hloov), thawb pas nrig ntsaws ruaj ruaj (tag nrho cov kev hloov pauv kom tsis txhob muaj kev puas tsuaj rau lub xeev kom tsis txhob muaj kev puas tsuaj. ntawm qhov tshiab.
By ua raws li cov ntsiab lus tshuaj xyuas saum toj no thiab ua tiav peb cov txheej txheem tseem ceeb, qhov ua tsis tiav ntawm kev lag luam nres tuaj yeem txo qis, lawv lub neej kev pabcuam tuaj yeem txuas ntxiv (feem ntau ntawm 2-3 xyoos txog 4-5 xyoos), thiab cov khoom siv kev nyab xeeb tuaj yeem lav tau.
